In this issue of Materials Technologies for Medical Devices we will look at the advancements made in the field of sensors, implants, drug delivery systems, adhesives and 3D printing and how scientists have modified their vision and approach in designing alternatives to current practices. Innovations in the field of bio-compatible adhesives to eliminate trauma caused by punching holes in tissues with sutures and screws, non-invasive sensors to monitor glucose levels using sweat, customizable 3D printed cast to avoid infections caused by plaster splinters and implants that can stick it out in the body and change the way we deliver drugs to the body.
